02Density altitude and turboprop runway margins

Standard temperature at 1,221 ft is about 13°C. Every 1,000 ft of density altitude adds roughly 8 percent to a turboprop's takeoff distance and 5 percent to its landing distance. The table uses Piper Meridian book numbers (2,438 ft takeoff and 2,110 ft landing over a 50 ft obstacle at sea level, ISA, max weight) as a reference airplane; heavier turboprops and light jets scale the same way from their own POH figures.

Conditions	Density altitude	Takeoff est.	Landing est.	Landing × 1.5
Standard day (ISA, 13°C)	1,221 ft	2,676 ft	2,239 ft	3,358 ft
Warm day (ISA +10)	2,421 ft	2,910 ft	2,365 ft	3,548 ft
Hot day (ISA +20)	3,621 ft	3,144 ft	2,492 ft	3,738 ft
35°C afternoon	3,914 ft	3,201 ft	2,523 ft	3,784 ft

Planning aid only. Even on a 35°C afternoon the longest runway (01/19, 9,072 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,784 ft needed). The percentages are a generic rule of thumb applied to one reference airplane, not certified performance data for any specific aircraft, and the runway size categories describe the runway, not your airplane's suitability. Verify with the approved flight manual before every flight.

03Nearby fields with 5,000 ft or more

Useful as alternates, as fuel stops when the price at KSAW is high, or as the longer runway on a hot afternoon.

04Jet A prices and FBOs at KSAW

No public API publishes FBO fuel prices, so JetDesk does not guess. Pilots and crews log the price they actually paid at KSAW, the app flags a price stale after two weeks, and the route finder ranks every field within a corridor of your route by net savings after the cost of the extra cycle. Log a price at KSAW or read what a fuel stop actually saves.
